Abstract

A system for detecting and converting vehicle information for display includes a device including a first port and a second port. The first port being configured for communicating with a port of a vehicle to receive an input signal and the second port being configured for communicating an output signal from the device to a gauge. The system also includes a processor operatively coupled to the device. The processor is in communication with the first port and the second port is configured to read data from the input signal received at the first port, convert the data from the input signal to the output signal, wherein the output signal has an analog format, and output the output signal from the second port to drive at least one vehicle gauge.

Claims

1. A system for detecting and converting vehicle information for display, the system comprising:

a device including a first port and a second port, the first port being configured for communicating with an port of a vehicle to receive an input signal, the second port being configured for communicating an output signal from the device to a gauge;

a processor operatively coupled to the device, the processor being in communication with the first port and the second port and being configured to read data from the input signal received at the first port, convert the data from the input signal to the output signal, wherein the output signal has an analog format, and output the output signal from the second port to drive at least one vehicle gauge.

2. The system of claim 1, wherein the first port is configured for communicating with an OBD2 port of a vehicle.

3. The system of claim 2, wherein the OBD2 port is in communication with an electrical control unit of a vehicle.

4. The system of claim 1, wherein the output signal is in a configurable analog format.

5. The system of claim 4, wherein the at least one gauge is an analog gauge.

6. The system of claim 1, wherein the output signal is in an analog electrical format.

7. The system of claim 6, wherein the at least one gauge is an electrical gauge.

8. The system of claim 1, wherein the input signal comprises sensor values received from an onboard computer system of the vehicle.

9. The system of claim 1 further comprising operating parameters operatively coupled to the processor for configuring the operation of the system to convert the input signal to the output signal.

10. The system of claim 9, wherein the operating parameters of the system are received from a personal computer program operatively coupled to the device that configures the operation of the system.

11. The system of claim 9, wherein the operating parameters are combined mathematically to synthesize a new parameter, and the new parameter drives the at least one vehicle gauge.

12. The system of claim 11, wherein the new parameter calculates fuel economy from various operating parameters and the output signal is configured to activate a lamp when fuel economy is below a predetermined threshold.

13. The system of claim 1, wherein the output signal is configured to activate a check engine lamp.

14. The system of claim 1, wherein the output signal drives a relay when a parameter is above a certain value.

15. The system of claim 1, the output signal drives a relay when a parameter is below a certain value.

16. The system of claim 1, wherein the output signal activates a lamp when a parameter threshold is above a certain value.

17. The system of claim 16, wherein the lamp is a “

shift light”

when RPM exceeds a certain preset value.

18. The system of claim 1, wherein the output signal activates a lamp when a parameter threshold is below a certain value.

19. The system of claim 18, wherein the lamp is an “

oil light”

when engine oil pressure is below a certain preset value.

20. The system of claim 1, wherein the processor is pre-programmed to support predetermined functions or gauges out of the box.

21. The system of claim 1, further comprising an external storage interface, wherein the external storage interface is in communication with the processor and an internal storage device for later retrieval and analysis by the user.

22. The system of claim 1, further comprising a wiring harness connected to the device and having an analog communication connection, a power connection, and a ground connection.

23. The system of claim 22, wherein the wiring harness provides the output signal for the at least one gauge.

24. The system of claim 23, wherein the wiring harness provides the input signal from the vehicle to the first port.
